This'clutch comprises a clutch member 31 actuated 7Vas by means of a clutcharm 32 se'- qu'red to a clutch operating shaft 33 rotatta'bly mounted ina frame constituting the legs or table support at this end of themachine. The shaft 3.3 is rotated to effect engagement of the clutch`member as bymeans of a cord 34 or -similar flexible connectionextending from a treadle 35 pivotally supported on a rod 36 secured toand extending between the legs or supporting frames at opposite'ends ofthe machine. The cord 34 passes over a sheave 37 and to one arm 38 of alever secured vtoand projecting from the shaft 33, and as shown inFigures 5, 6 and 7 of the drawings. The other arm of said lever has aspring 39 secured at one end thereto, the opposite end of said springbeing secured to one of the legs 11, said spring holding the members ofthe clutch mechanism disengaged, and the treadle 35 being employed toengage the clutch members for'the `purpose of starting operation of thesewing machine. Y v v f The presser foot of the sewing machine isautomatically actuated by the "mechanism just described for startingandst-opping the machine, this presser foot actuating mechanismcomprising a presser foot actuating lever 40 having 'one arm underlyingthe end oa presser foot actuating rod 41 connected 'with the 'presserfoot in any suitable manner to cause said foot to be loweredin-theoperationof the mechanismr to start the `machine kkandto ybe raised inthe operation of stopping machine. lIn`V the arrangement herein shownthe other arm of said lever is connected by a rod 42 with the machinestarting arm 38 hereinbefore mentioned so that when ysaid. arm 38 isactuated to start the machine the presser foot will beautomaticallylowered and vice The mechanism forcutting and severing measured lengthsofk material, as hereinbefore referred to, comprises a frameadjustablymounted to produce kmopsofdiierent lengths, said fframemovably supporting. a cutter for operation thereof. rSaid frame comrises'an end 43 located atV the back of the mac ine, a top 44,-sides 45,and tie bars 46. The end 43 has a shoulder 47 extending across Yit fromedgeto edge, saidshoulder being seated upon a bar comprising ay guideX48 secured to lugs projecting from a depending iiange at.r the back ofthe table 10, .and as Yshown in Figures 3 and 4 ofthe drawings.

A gib 49 is-secured to the front side'of the bracket orend43p'andprojects downwardly below the shoulder k47. This gib has a screwVthreaded stud engaged by the screw threaded hub of a clamp wheel 50 bymeans of which the'gib'is clamped against the guide 48 to holdA`the-cutter frame in any position to which it kmay have been moved. Asupport 51 in the form of a lip projecting downward ly from the front ofthe top 44 rests upon a ledge 52 projecting from the back surface of atiange 53 extending downwardly from the top 10 at the front of themachine. The tie bars 46 project through lugs 54 extending from vthelower edges of the sides 45 and also through lugs 55 projecting from theopposite edges vof the frame end 43, nuts upon the lends ofthe barsserving as a means for rigidly securi the4 frame parts together. Theframe end`4 is supported bythe shaft 12 that extends throughholesysuitably formed in branches 56 at the lower edgey of the frame therebyenabling the cutter frame to be adjustably positioned for the purpose ofcutting mopsof different lengths. A cutter support 57 in the form of abarframe is loosely su ported on the shaft 12 for adjaustable sli ingmovement thereon, the bearings for said support comprising ears 58through which the shaft extends. A cutter driving pulley 59 -issplinedto the shaft 12 between the ears 58 and a belt 60 extends from saidpulley to a'pulley 61 secured to the .shaft of a cutter 62y rotatablmounted in bearings 63 in branches extends: ing fromr the front end ofthe supporty 57. The support 57 normally rests so that the upper edge ofthe cutter 62 is below the table 44, this position'of rest beingdetermined by a cutter positioning screwv 64 rotatably secured at itsupper end in a lug projectingy from the under side of the top 44,'and asshown in Figure 4 ofthe drawings. This screw rotatablyV engages asupporting loop k65 having an o emng into'which a lug at the front end oonefof the sides'of the support 51 extends, this lug being forked toextendon opposite sides of the screw 64, and as shown in Figures 3 and 4ofthe drawings. 'Y In order to minimize the amount of power required toswin the sup ort 57 on its ivot at the rear en thereo va counterba anceweight' 66 is suspended fromone end of a cord 67, the opposite endofsaid cord being secured to the support 57after passing overy sheaves ymounted in `lugs `projecting from the under side of the top 44,`and asshown in Figure 4.0i the drawings. v

When the cutter 62 is raised to cut armass of mo material in a manner tobe hereinafter escribed, it is projected through a slot 68 in the top 44and in order to avoid accident to a person when the cutter is thus pro,-j ected, afguard is automatically lowered over `the slot 68 toenclosethe vedge of thelcutter vprojecting through said slot. comprisesa Vhood 69 supported to rto This guard a slight extent between the sideparts of a hood supporting frame 70 pivotally mounted at its rearf end.on aylug 71k extending from end, these branches loosely receiving theshaft :Lemans the 4upper yedge yof the bracketor frame `end,

43 preferably'at one side thereof. v A hood actuating rod 72is pivotallycon nected at itsupper end toa cross piece eX-. 5 tending between theside parts of the supportf:

i ing frame 70, the lower end Vof said rod being l securedto an ear onthe side of a `cylinder 73.

This cylinder contains a-piston of any ordinary form havinga piston rod7 4 pivotallyV 10 [attachedv'tooneof the side parts of the support 57.Av lexiblehosezor tube 75 extends from the lower end of the cylinder 73into the base'of a cylinder-76 supported, as on aV floor, this cylinderV7 6 having a piston of any ordinary constructionl therein from which apiston rod 77 extends, the uppery end of said rod being `pivotallyattached to vone end of a yraised positions. n i

When the pedal 79 ispressed down, as by ythe foot ofthe operator of themachine, inward movement of the piston in thel cylinder 76 will, throughthe tube 75, create pressure f inthe bottom ofthe oylinde1fi7 3 whichpres-` sure will act in .opposite directionsLagainst:

thek bottom ofthe c linder 73 and piston therein.. The strengt A"of thespringl 82 .is

such that resistance to downward movement` of the cylinder 73 islessfthan the resistance to upward movement of the support 57,wherefore" .the pressure in thek cylinder7 3 Vwill cause the latterandthe frame 7 0 to be moved 'downwardly tocause the'hood ,69` to coverthe cutter 62. When the hood "comes in Contact :with the upper surfaceof thetop ofthe cylinder 73 is prevented whereby the pressure in thecylinder will now act to force y.the piston outwardly therebymoving thesupport-57 and the cutterlthereon upwardly, the latter through the slot68,' thereby ysevering the "mass ofk threads projected across said slot.AUpon release ofthe p'edal7 9 al reverse action of the parts willtakevplac`e,thus.re-

storing the cutter and-hood to their normal positions, ythe cutter beingmoved. vdownwardly from within the slot before thejhood moves upwardlyto uncover the slot.V l

The tape 24 is nowy wrapped about `the length 22 of materialxand thewhole is slidable under the needle ofthe sewing machine and maybemanipulated to sew the parts to'- gether in such manner as may bedesired.

613'k It will be noted that an opening 80 is made in the table l() andthat the` top 44: of the cutter `frame projects through this openingsubstantially closing-itV except as to one'sider thereof.
